1 Claim.

crown gears will be allowed to shift out of mesh.

Considerable trouble with the loom is, therefore, experienced. with consequent large expense for upkeep.

One object of my invention is, therefore, to provide a cam shaft box support which will engage and effectively retain the 'cam shaft box inproper position at all times so that the crown and head gears will always be kept in proper mesh.

Another object of the invention is to provide a device :of this character which is capable of ready adjustment.

A further object of the invention is to provide a cam shaft box support having a body, the entire upper surface of which will engage the lower edge of the cam shaft box so that a uniform solid bed or support-for the box will be assured.

A further object of the invention is to provide an attachment of this character which is capable of easy installation and wherein means are employed for permitting adjustment quickly and efficiently.

Other and incidental objects of the invention not mentioned hereinbefore will become apparent as the description proceeds.

My invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation, partly in section, showing my invention as it would appear properly installed on a loom end, and

Figure 2 is a perspective view of my cam shaft box support, the adjusting screw and lock nut being shown confronting the opening.

Referring now more particularly to the drawing, wherein similar numerals of reference will be seen to designate like parts throughout the various views, the numeral I indicates the end of a loom. The loom I has supporting legs 2 and 3 which are connected by a web 4. The web 4 has a laterally extending flange 5 and the leg 3 has a laterally extending flange 6. Mounted in the loom is a cam shaft 1 which cam shaft is supported by a bearing 8, mounted on a box-9. Bolts I0 secure the box 9, with bearing 8 thereon, in position on the end of the loom I.

My improved cam shaft box support includes a body II which comprises a single casting. The body II has an arcuate lower wall I2 and a straight upper top wall I3. The straight front wall I 4 whi'ch'is disposed at right angles to the top wall I3 is provided for the body. The body II is also provided with an offset portion I5 and a curved rear wall I6, said wall I6 having a flat portion IT at its upper end portion. Formed in the body II near the front wall I4 and disposed obliquely with respect to the top wall I3 is an elongated rectangular slot I8. As best seen in Figure 2 of the drawing, the inner end of the slot I8 is the lower end thereof. 'A second slot I9, of the same contour as the slot I8, is formed in the offset portion I5. The slot I9 is arranged in the same manner as the slot I8. That is to say, obliquely with respect to the horizontal, the lower end of said slot being the one nearest the bottom wall of the offset portion I5.

Formed in the body II between its faces and extending from the portion ll of the wall I6 inwardly, and parallel to the top wall I3, is an internally threadedopening 20. The opening 20 removably receives an adjusting bolt 2I which has a squaredhead 22 formed with a flat end surface 23. As best seen in Figure l, the bolt is carried in the opening 20 and is locked in'position therein by a lock nut 24.

In use, my improved cam shaft box support is mounted in the position shown in Figure 1. That is to say, the device is mounted with the bottom wall I2 in engagement with the flange 5 and the top wall I3 engaging the lower edge of the box 9. Bolts 25 are extended through the elongated slots I8 and I9 and into the ends of the loom I It is desired to call attention to the fact that, inasmuch as the slots I8 and I9 are elongated, the body II may be shifted along the flange 5 for raising or lowering said body, and consequently the top wall I3, to desired positions. For effecting the raising of the cam shaft box, it is only necessary to rotate the bolt 2I in a counterclockwise direction, when the face 23 will be caused to abut the flange 6 of the loom end and rotate thereon. As the bolt 2I unscrews in the opening 20, the body II will be shifted upwardly for urging the top wall I3 into tight engagement with the lower edge of the cam shaft box so that said cam shaft box will be positioned properly for retaining the crown and head gears in proper meshing relation. The lock nut 24 together with the bolts 25 will retain the device in proper position until such time that it may be necessary to change the adjustment.

My improved cam shaft box support may be used at either end of the loom and, as will be obvious, may be installed with the utmost facility. Furthermore, as the top wall I3 has its entire length in engagement with the lower edge of the box 9, a firm mounting will be assured for the box. The device is characterized by the utmost simplicity and by the fact that it is capable of adjustment, by the one bolt 2|, with the greatest of ease.

Having thus described the invention, what is claimed as new is: I

In combination with a loom having flanges,

one of said flanges'being arcuate, and a 'cam' ing an arcuate lower wall for engagement with,

the arcuate flange, and a top wall engageable with the cam shaft box, said body having inclined elongated slots therein, bolts extending through the slots and into the loom for adjustably mounting the body on the loom, and an adjusting bolt carried by the body and extending between one end thereof and the other of the loom flanges, said adjusting bolt being rotatable for shifting the body, upon loosening of the first mentioned bolts, on the arcuate 'flange', for raising the cam shaft box to take up wear.
